You've heard of Big Business and Big Agriculture and Big Tobacco. Maroon is Big Toon. As the head of Maroon Cartoons, he appears to be the boss of all Toons. He cranks out cartoons like China churns out iPhones. And he has no guilt about selling out all of the Toons to make himself richer. What a jerkbag.
Maroon acts like he has the Toons' best interests at heart, but by resorting to blackmail in order to score an advantageous sale for his studio, he empowers Judge Doom to take over Toontown and kill the Toons.
In a movie like this, Maroon ends up getting what's coming to him—and that's a bullet in the back.
